Abstract: An optical turbulence measurement system may include a camera assembly, a first optics assembly, a second optics assembly, and processing circuitry. The first optics assembly and the second optics assembly may be configured to magnify and direct a portion of a source beam received by a respective aperture to the camera assembly to be received as a two portions of a received beam. The processing circuitry may be configured to receive, from the camera assembly, a data representation of a first received beam from the first optics assembly and a second received beam from the second optics assembly, determine a focal spot displacement variance based on motion of a first focal spot corresponding to the first received beam relative to a second focal spot corresponding to the second received beam, and measure optical turbulence along a path of the source beam based on the focal spot displacement variance.

Abstract: A system device and method for storing paint in which paint (2), either at a paint store or at home, is placed in a storage bag (1) that is sealed to create one or more packets (10). The packets may then be stored for use at a later date for touching up damaged or marked paint on walls and other surfaces.

Abstract: An active optical detection system includes an optical transmitter configured to transmit light in a signal pattern and an optical receiver configured to receive light and determine a correlation between the received light and the signal pattern. The correlation of the received light and the signal pattern is indicative of range to an object.

Abstract: Example apparatuses and methods are provided that improve laser performance or decrease the frequency or severity of the occurrence of Stimulated Brillouin scattering. One example is a laser device that may include a seed laser configured to generate an optical output, a pattern generator configured to generate a modulation pattern, and a phase modulator configured to apply a modulation scheme to the optical output based on the modulation pattern. The modulation pattern may include a digital sequence and the modulation pattern may be applied to modulate a phase or an amplitude of the optical output.

Abstract: The present invention is directed to a device and a laser, eye-safe method for laser marking slides for use in conjunction with a light microscope. The device is an attachment for a light microscope that allows the operator to make marks on preparations of biological tissues or other materials placed on a glass slide or between a glass slide and a cover slip. The marks can be used to indicate or highlight a microscopic structure or feature of interest. The marking on the slide is performed as the specimen is examined, without having to remove it from the microscope stage. In this way the invention has application in a biomedical or pathology laboratory for diagnostic, research, archival, and teaching or training purposes.
